Z4 Roadster (E85) iPhone aux jack radio dice mod install

I have a 2003 Z4 with the Business CD radio and purchased a dice module Bluetooth/ aux/iPhone kit. In the videos I've watched they state that there should be a 3 pin & a 6 pin plug ins in the trunk to hook into the module but I can't seem to locate them. I see the wiring harness and followed it through the pass through and into the battery compartment but no extra wires anywhere. I'm now wondering If this is not possible On a 2003 model? Can anyone help? Thank you

Check with the dealer and see if yours is pre wired for a disc changer. I have the same install in my 2005 the wires were taped under the oddements box

Thanks. Ill check again under there but what's the oddements box?

The center console between the seats.
